How is command transmission carried out and what security measures are applied?

Command transmission in DevOps is usually carried out through remote access and automation protocols, such as SSH (Secure Shell), API calls, or configuration management systems (Ansible, Puppet, Chef).

To ensure security, the following measures are applied:

• Encryption of communication channels (for example, SSH uses cryptography to protect data).
• Authentication and authorization: using SSH keys, tokens, passwords, roles, and access rights.
• Logging and auditing: recording all executed commands for subsequent analysis.
• Access restriction: configuring firewalls, VPNs, IP address restrictions.
• Use of secure protocols and software updates to prevent vulnerabilities.

Example: when executing a command on a remote server via SSH, a key is used for authentication, and all traffic is encrypted, preventing interception and command substitution.
